Title: Piston drive transmission structure in a rotary compressor
Inventor: CHEN RULING
IPC: F04C29/00
Filed: 1986-12-13
Abstract: An electric motor driven shaft 23 directly actuates a rotary drive disc 24 with an integrally moulded crank pin 25 which actuates a piston disc 26 with a motion of eccentrically rotary stroke. A plurality of bearing rollers 28 on the outer peripheral surface of the piston disc 26 actuate a surrounding piston element 22 with a synchronous motion of eccentrically rotary stroke rolling on a cylinder wall 29, so as to decrease the frictional resistance at the cylinder wall 29 during suction and compression, save horse-power and enhance efficiency. <IMAGE>
Patent GB-869087-A (GB)
Abstract: 869,087. Preparing halo-hydrins electrolytically. STANDARD OIL CO. Dec. 8, 1959 [Dec. 29, 1958], No. 41745/59. Class 41. Aliphatic and alicyclic halo-hydrins are formed by electrolysis of an α-# unsaturated aldehyde or ketone preferably of 3 to 8 C atoms, dissolved in water containing a hydrogen halide e.g. HC1, HBr, or HI. Soluble halide salts may be added. The starting materials include acrolein, crotonaldehyde, methyl vinyl ketone, mesityl oxide, and 2-cyclohexanone, and an aqueous solution containing up to 10% of the material is used. Preferably cadmium is used as cathode, and carbon or platinum as anode, both electrodes being in the form of flat plates. A battery of such cells may be used, no diaphragm being necessary. In examples, acrolein is added at intervals to HBr solution containing a little cadmium bromide contained in a cell operating at 2-7 volts and at 40‹ C. At the start of electrolysis the current is reversed for short periods. Further amounts of reactants are added over a period of 11 hours. The products separated by distillation contained glycerol mono- and di-brom hydrins. The corresponding iodo- and chloro-derivatives obtained from acrolein and crotonaldehyde are also described.

Title: Control of burner air/fuel ratio
Inventor: BROWN NORMAN DAVID
IPC: F23N1/02
Filed: 1987-05-06
Abstract: The emission intensities of at least two of the species C2, CH and OH in the burner flame 8 are sensed by a pair of photodiodes 5 and 6. The ratio of the intensities of the species are calculated by a microprocessor 10 and compared with a predetermined range of intensity ratios stored in the microprocessor 10. The stored range of intensity ratios corresponds to that necessary for the flame to be adequately aerated but neither excessively over-aerated nor excessively under-aerated. An error signal is generated if the calculated ratio falls outside the predetermined range of intensity ratios and is used to control the rate at which gas enters the burner 4 via a fuel injector 14. <IMAGE>

Title: Cache memory having sub-arrays of cells
Inventor: PARTOVI HAMID
IPC: G06F12/10
Filed: 1991-03-26
Abstract: The physical organization of a memory cell array in a cache memory is made different from its logical organization by segmenting the bit lines to divide the array into sub-arrays 120, and multiplexing the bit lines to data lines (super-bit lines). By dividing the bit lines, the number of "late" address bits is increased relative to the number of "early" address bits, to increase the memory access speed in data processing systems that employ virtual addressing but store data in cache memory in association with physical addresses. Routing problems are avoided by extending the data lines in parallel with the bit lines over memory cells, and forming the data lines in a metalization layer separate from and over the metalization layer of the bit lines. Each data line is multiplexed at 78, 135, 137, to multiple bit line segments 131, 132, 133 to eliminate a final multiplexer to input/output lines. <IMAGE>

Title: Radiation sensor
Inventor: ALDER CHRISTOPHER JAMES
IPC: H01Q21/00
Filed: 1991-07-25
Abstract: A lens 12 has two parallel focal planes 26a, 34, these being defined by a polarization-selective reflector grid 18 within the lens 12. One focal plane 26a is occupied by a receive array (100, Fig. 5 not shown) of crossed dipole antennas (102) with respective mixer diodes (eg 106a). One dipole of each antenna (102) couples to a local oscillator signal and the other couples to a receive signal reflected by the grid 18. These signals are mixed by the diodes (eg 106a) to produce intermediate frequency signals for subsequent processing. The other focal plane 34 is occupied by a transit array (70, Fig. 2 not shown) of separately activatable polarization switching antennas (72) arranged to define a range of transmit beam directions. This focal plane 34 may alternatively be occupied by a second receive array (270, Fig. 8 not shown). For use particularly at microwave and millimetre wavelengths. <IMAGE>

Title: Spent caustic treatment
Inventor: DEROECK ROBERT L
IPC: C10G70/06
Filed: 1992-02-04
Abstract: A process is provided for treating a sulfide-containing alkaline aqueous effluent to improve its environmental acceptability, which comprises: (a) intimately mixing a water-immiscible solvent, such as a pyrolysis gasoline, therewith for a sufficient time to extract polymerisable hydrocarbon compounds and/or other compounds which may cause fouling of downstream plant, (b) allowing the solvent phase and the aqueous phase to separate, (c) removing the solvent phase, and (d) subjecting the separated aqueous phase to an oxidation treatment which oxidises sulfide ions to environmentally acceptable sulfur acid ions, particularly sulfate ions, e.g. a wet air oxidation process. The invention has been particularly developed for treating spent caustic which has been used to scrub gases produced by cracking for ethylene production. Such effluents have been found to cause fouling of the oxidation plant and the Applicants have found that this is due to polymerisable hydrocarbons. Furthermore they have found that prolonged contact times between a readily available solvent and the effluent can ensure that the fouling problem is cured.
